When you need it to be right, every time. When reliable print quality matters. When appearance and smoothness demand consistency. Then, rely on DiamondTop®. Constant quality is woven into every roll to ensure printed graphics of the highest quality. Whether your package is headed to a warehouse or directly to a retail shelf, graphics get noticed with our DiamondTop®.
DiamondTop® is a multi-ply sheet with a white printing surface over a kraft base sheet. Designed for post print and direct print applications, DiamondTop® provides a smooth, bright surface for high quality, multicolor graphics typically used in retail-ready corrugated consumer packaging.
DiamondTop® 1C enables high print gloss and rich ink density and offers reliable and consistent runnability and convertibility. Featuring a light clay coating, it’s post-printable in many cases without the aid of dryers and it’s suitable for the graphic demands of preprint applications.
DiamondTop® 2C is a solid bleached sulfate (SBS) sheet designed specifically for the demands of roll-fed, preprint, flexographic printing. Offering a smooth, bright, double clay-coated printing surface, DiamondTop® 2C enables high-quality printability for outstanding graphic reproduction. Engineered for strength, it resists cracking while meeting box ECT requirements.
DiamondTop® High Performance offers the high-quality printability of DiamondTop® with the performance of standard liners, but at lower basis weights.
DiamondTop® Solid is excellent for applications where the highest levels of print gloss are not required. It features a single-ply sheet of bleached fibers produced with moderate calendaring, and an added surface treatment ensures optimal ink hold-out. This linerboard is ideal for solid coverage printing and it is also well suited for the clean, white packaging needs of high-end markets such as pharmaceuticals or retail.
DiamondTop® WX, a multi-ply sheet with a white printing surface over a kraft base sheet, is optimized to retain a white appearance even when the sheet is coated or saturated with wax.
DiamondTop® WS, a multi-ply sheet with a white printing surface over a kraft base sheet, is designed to provide added strength under damp conditions and is beneficial for post print or direct print packaging that must undergo extreme transport or storage conditions.
DiamondTop® HZ is designed for HazMat packaging. It provides a smooth, bright surface for printing high quality, multicolor graphics typically used in retail-ready corrugated consumer packaging.
